I am using the Nucleo-L4r5zi with the octospi peripheral to communicate with a qspi NAND flash chip (W25N01GVZEIG). The octospi peripheral is set up in status polling mode to poll the state of the Write Enable bit in the flash status register. This i...
That is my code below (Nucleo STM32L053). RTC works from 32768 quartz (LSE). Blue Button disconnected by eliminating of the SB17. Additional LED is connected to PC13 instead of the button. So, the device wakes up normally, when I set high level on wa...
My controller can be waked up from Standby mode by Alarm A or Alarm B: Alarm A every day and Alarm B every minute. Are there any flags (or another means) to know, what event (Alarm A or B) was cause of the waking? That is the problem, because all re...
according to the manual it says 4 Kbytes of backup SRAM in D3.D3 start address is 0x38000000in manual address for backup RAM is 0x3880 0000but below is the behavior observed.code example. __HAL_RCC_BKPRAM_CLK_ENABLE(); HAL_PWREx_EnableBkUpReg(); HAL...
Hello,I have generated a default project with cubeIDE for a nucleo L433RC. I have only enabled LPUART1 with default parameters. I just change the baud rate to 115200.I add in the main : /* Infinite loop */ /* USER CODE BEGIN WHILE */ char out[6...
hi, Reading the UM2397 manual on page 12 chapter "Power supply" describes the possibility of powering the core through Vin in a voltage range of 7V-12V, I power it at 10v (the power supply can supply 500mA sufficient current for a core). The card the...
I am planning to interface 4 numbers of Wiz830MJ modules with STM32L496 using FMC SRAM interface. Is there a need to have buffers for address bus and transceivers for data bus. OR else Can i manage without these buffers/tranceivers ?
the atteched file mbxfirmware_ebike is our solution code . we have three projects .and I am doing the bootloader testing . the mbxEbike is my application project ,and I set #define VECT_TAB_OFFSET 0x8000 /*!< Vector Table base offset field.in this...
I heard that RT-Thread has released a new IDE: RT-Thread Studio. Has anyone used it ? I heard it was great.
I have configured the TIM3 in input capture with following configurationPrescale - 1Period - 0xFFFFCounter mode- UpDivision - 0Repetation counter - 0ISR reads the counts accurately if the encoder signal frequency is within 100KHz, but increasing the ...
